Cognitive and behavioral modernity in Homo erectus: skull globularity and hominin brain evolution

In this article we provide evidence that evolutionary pressures altered the cranial base and mastoid region of temporal bone more than calvaria in transition from H. erectus to sapiens. This process seems have resulted evolution globular skull shape – but not as a result expansion brain parietal regions reduction relative parietals. Consequently, argue parietals be unrelated evolution, is by-product other skull, may related dietary factors. Additionally, these findings suggest cognitive behavioural modernity necessarily dependent on shape. Also, it cannot attributed change size because modern human capacities overlap substantially. possessed full suite adaptations characteristic humans without possessing with flared Our results also support theory paedomorphic morphogenesis was important sapiens such changes both factors social evolution.
